A multilayer ceramic capacitor includes a multilayer body including dielectric layers and internal electrode layers stacked together, and external electrodes. The multilayer body includes an inner layer portion and outer layer portions in a stacking direction, and an electrode opposing portion and gap portions in a length direction. The multilayer body further includes conductor portions in the two outer layer portions in the gap portions, and each includes conductor layers stacked in the stacking direction. One of that conductor layers that is closest to a middle in the stacking direction of the multilayer body is closer to the middle in the stacking direction of the multilayer body than another of the internal electrode layers closest in the stacking direction to a main surface of the multilayer body.

Multilayer ceramic capacitor

When internal electrode layers are viewed in a stacking direction, the internal electrode layers include an internal electrode main body portion defining an effective region, and an internal electrode lead-out portion that leads to a first or second end surface of a stacked body, and a length of the internal electrode lead-out portion in a width direction of the stacked body is less than or equal to about &#xbd; of a length of the internal electrode main body portion. The internal electrode layer includes a first region having relatively high continuity of a conductive component defining the internal electrode layer, and a second region having relatively continuity of the conductive component. A central portion of the internal electrode main body portion is defined by the first region, and a portion of the internal electrode lead-out portion is defined by the second region.

A method of manufacturing a multilayer ceramic electronic component includes preparing a green mother laminate in which ceramic layers and inner electrode layers are stacked; cutting the mother laminate perpendicularly or substantially perpendicularly to a main surface of the mother laminate and in a first direction when the mother laminate is viewed in plan such that first sectional surfaces are formed, and pressing the mother laminate to obtain a bonded laminate in which the first sectional surfaces are bonded to each other; and separating the bonded laminate between the first sectional surfaces to obtain laminates. Then, the bonded laminate is cut perpendicularly or substantially perpendicularly to the main surface and in a second direction that intersects the first sectional surfaces such that second sectional surfaces are formed.
